Fascinating! What sort of restrictions are you talking about? I don't recall seeing any in the PHB!I can somewhat forgive this though, given that Paladins have the most roleplaying restrictions of any class, besides maybe Warlock. The party needs some reason to keep that stubborn bastard around.
On top of all that, the interaction of smite with the crit rules means a paladin wanting to be a little more conservative in their use of spell slots can wait till they score a 20, then turn the smite into a double-damage blast.
And, on top of that, there is no per-turn limit to the use of smite, unlike most such features. So a paladin needing to pull out all the stops can use a smite on every hit; up to twice per round with Extra Attack, or even three times if you can arrange a bonus action attack (e.g., with Polearm Master).
I've a TWF Vengeance Paladin in my Eberron game, and even if I hadn't houseruled TWF Fighting Style onto the Paladin for her, she'd wreck face with Hunter's Mark, Oath of Emnity, and Smites-saved-for-crits.
